The mechanical damage accumulation occurring in an array of axially loaded nanopillars is studied within the stochastic approach. To each nanopillar, an initial strength--threshold is assigned which is drawn from the Weibull probability distribution. Under the influence of load exceeding the strength-threshold the pillar height is reduced. Then the reduced pillar gets new higher strength-threshold and its load is transferred to other working pillars. We analyse slip loads causing the system height reductions and avalanches of the pillar height reductions.
